	Polydactyly - Wikipedia, the free encyclopedia
		Polydactyly, or polydactylism, also known as hyperdactyly, is the anatomical abnormality of having more than the usual number of digits on the hands and/or feet.
		Polydactyly with cleft lip/palate and psychomotor retardation (Varadi-Papp Syndrome)
		Polydactyly postaxial with median cleft of upper lip

	Korean Journal of Radiology
		Among these 50 cases, five [polydactyly (n=1), syndactyly (n=2) and curly toe (n=2)] were confirmed by postnatal physical evaluation, two (focal spine anomalies) were diagnosed after postnatal radiologic examination, and the remaining 43 were proven at autopsy.
		Polydactyly, the condition in which more than five digits are present, may be classified as one of two main types: pre- or postaxial.
		Polydactyly may be accompanied by multiple structural anomalies such as cardiac malformations, the absence of the corpus callosum, cephalocele, and short rib-polydactyly (SRPD) syndrome (3).

	Polydactyly (Extra fingers)
		Polydactyly is one of the most common variations on the basic growth pattern of the hand.
		Certain types of polydactyly are associated with other birth related problems elsewhere in the body, and it is a good idea to have an evaluation for this reason alone.
		Surgery for polydactyly is usually best done in the first few years of life so that the look, feel and function of the corrected hand is the most natural for the child.

	Polydactyly In Humans and Other Species
		One effect of this is triphalangeal preaxial polydactyly (like Twisty Cats), 6 to 9 toes on fan-like feet, dwarfing, twisted and/or thickened limbs, short or missing tibia/radius, kinked tail, flattened ribcage and short, bulbous head.
		Breeds where the polydactyly trait is encouraged are those bred for working on snowy or uneven ground where extra grip is required.
		In horses, polydactyly has occasionally appeared in the form of small supernumerary digits terminating in hooves either side of the main hoof; these resemble the horse's evolutionary ancestors hence older texts refer to such mutations as atavism (throwback hrowback to ancestral stock).

		Polydactyly, or extra digits, is a common trait among cats, particularly it seems, among Celtic cats and cats on part of America's Eastern coast and South West Britain.
		Polydactyly is common enough in some areas of Britain for it to be almost unremarkable and I see several polydactyls per year at the Chelmsford Cats Protection rescue shelter as well as having owned a polydactyl.

	Treatment Options for Polydactyly - Dr. Netscher
		On occasion, because of joint surface malalignment (particularly when the duplication involves a shared joint in addition to the ligament and tendon readjustments) a corrective bony osteotomy may be considered.
		This procedure involves actually tacking the bone and resetting its angle and may be required at the initial correction of the polydactyly.
		While it is important to meet with the child at a young age, within a month or two of birth, the actual reconstructive surgery for polydactyly (digital duplication) will generally be performed somewhere around 9 or 10 months of age.

	Evolution: Library: Genetic Drift and the Founder Effect
		Polydactyly -- extra fingers or sometimes toes -- is one symptom of Ellis-van Creveld syndrome.
		The syndrome is commonly found among the Old Order Amish of Pennsylvania, a population that experiences the "founder effect." Genetically inherited diseases like Ellis-van Creveld are more concentrated among the Amish because they marry within their own community, which prevents new genetic variation from entering the population.
		One form of dwarfism, Ellis-van Creveld syndrome, involves not only short stature but polydactyly (extra fingers or toes), abnormalities of the nails and teeth, and, in about half of individuals, a hole between the two upper chambers of the heart.

		This study showed incidence of all types of polydactyly to be 2.3 per 1000 in white males, 0.6 per 1000 in white females, 13.5 per 1000 in fl males, and 11.1 per 1000 in fl females.
		Polydactyly rarely is associated with congenital anomalies, except in recognizable syndromes.
		Once polydactyly is established, a thorough ultrasound evaluation, especially of the heart, nervous system, limbs, and kidneys, to identify an associated syndrome, such as Meckel Gruber syndrome and trisomy 13, should be performed.

		Temtamy and McKusick[2] in their classification of polydactyly used as the major criterion whether the polydactyly was isolated or part of a syndrome.
		As with polydactylism in general, crossed polydactyly must be expected to occur either as an isolated phenomenon or as a part of syndrome and are rare.
		Crossed polydactyly was present only in 45 cases and most common among them was Type I. family history was positive in 12 cases, one patient had consanguineous parents.

		Polydactyly is a congenital anomaly of digit duplication caused by the mutation of genes involved in limb development.
		Differently from other polydactyly model mice mes does not show syndactyly or oligodactyly, therefore this mutant is an exellent model to study the mechanism of preaxial polydactyly.
		We hypothesize that preaxial polydactyly in mes is caused by the outgrowth of anterior region of limb bud diectely or indirectly by the truncated Ptc.

	Re: Why is the trait for polydactyly dominant??
		Polydactyly (an abnormal numbers of digits) can be associated with over 150 different conditions, and, occasionally, can be inherited in some familial conditions as a dominantly inherited trait.
		Frequently, polydactyly is part of a more complicated picture (or syndrome) in which other abnormalities are present.
		In families with isolated inherited polydactyly (no other abnormalities) 50% of an affected indvidual's children will also have this trait, so in this family the number of children with 5 digits would be equal to those with more that 5.

		Polydactyly generally can express itself in the form of either extra toes of fingers in the same family, although the type of polydactyly is generally constant.
		As polydactyly is said to be not passed on in terms of simple Mendelian inheritance, we say that it is multifactorial.
		Additionally, postaxial polydactyly is further classified according to the degree of formation of the duplicated digit.

		Pathophysiology: Postaxial polydactyly (lateral ray) is the most common polydactyly, occurring in 80% of cases, followed by preaxial polydactyly (medial) and then central polydactyly.

	BBC - Health - Ask the doctor - Polydactyly
		Of course, it's very worrying and stressful when your child is born with something unusual and unexpected such as extra toes, but in most cases this isn't actually very significant in terms of general health and may not need any specific treatment.
		Very occasionally polydactyly is part of an inherited condition such as Laurence-Moon-Bardet-Biedl syndrome (a rare and complicated disorder), but your paediatrician should have checked for any other abnormalities which would indicate this.
		But there are probably other people in the public eye with polydactyly who don't draw attention to it.

		Four types are: (1) thumb polydactyly, (2) polydactyly of triphalangeal thumb, (3) polydactyly of index finger, and (4) polysyndactyly.
		Although the evidence suggests that polydactyly is in large part genetically determined, it was difficult to choose between a single autosomal dominant gene with reduced penetrance and a multigenic threshold model involving a few major genes.
		(1985, 1987) suggested that a minor expression of thumb polydactyly is aplasia or hypoplasia of the thumb musculature and that this trait may more often be autosomal dominant than one would realize from a study of polydactyly alone.
